The Aeronautical Information Publication (AIP) contains most of the information about the regulations, air ways, navigation aids etc. in a nations air space. The AIP is published by that nations air authority or agency at regular intervals and together with notices to air men (NOTAMs) it contains all the information needed, except for the weather, for flying in that airspace unless it states otherwise.

Main contents

The AIP consists of three main parts, General (GEN), containing some general information, En route (ENR), containing information about the airspace, air routes and navigation aids, and Aerodromes (AD), with information about the airports, airfields and helipads. Sometimes there is also amendments and supplements, and the AIP can also point to other sources for example for aerodrome information and charts.


  • GEN 1. National aviation authorities, national regulations regarding entry and exit of the air space and required instrumentation and radios
